Skip default type parameters with _

(needed an issue number for tests)

Allow this:

function main() {
    var a:A<_,Int>;
    $type(a); // A<String,Int>
}

typedef A<K = String, V> = haxe.ds.BalancedTree<K,V>;

Uhm, did we agree to do this? I can't remember...

[kLabz]

Well, I did agree with myself there :grin:

iirc you were mostly worried about that syntax being potentially useful for something else, but I don't remember what

Random idea: A<default, Int>.
